AI Email Assistant with Smart Reply Drafting
An autonomous email assistant that monitors your inbox, understands conversation context through persistent memory, and drafts personalized replies using multi-provider LLM routing for optimal cost-quality balance.
Email Integration Layer
Handles secure OAuth connections to Gmail/Outlook and triggers workflows on new messages
Memory & Context Layer
Stores user preferences, writing style, and conversation history across email threads
Workflow Orchestration Layer
Visual automation engine connecting email triggers to AI generation and delivery
AI Generation Layer
Multi-provider LLM routing with cost optimization and structured output validation
AI Gateway routing simple 'thank you' replies to cheap models (GPT-3.5/DeepSeek) and complex negotiations to premium models (GPT-4o/Claude). Provides virtual keys for cost tracking and automatic failover if providers are down.
Visual AI workflow builder with RAG capabilities. Alternative to code-heavy LangGraph for teams preferring drag-and-drop prompt engineering and built-in review UIs.
Observability & Quality Layer
Monitoring, evaluation, and safety guardrails for production deployment
LLM-specific observability tracking every generated reply, cost per email, and latency. Essential for debugging tone issues and optimizing prompts based on real usage patterns.
Vector database for storing email embeddings if semantic search across historical emails is needed for context retrieval (e.g., 'what did I promise this client last month?').
